Description

Results of a major seeding research project conducted in Saskatchewan during the 2000, 2001 and 2002 growing years were presented in the report The Effect of Nitrogen Fertilizer Placement, Formulation, Timing, and Rate on Greenhouse Gas Emissions and Agronomic Performance. This detailed Research Update presents a preliminary summary of the findings, with with a special focus on an agronomic comparison of mid-row banding and side-banding systems.

Description

Dugouts provide water for a variety of purposes. They can be used as a source for domestic (household) water supplies, livestock watering, as well as raising fish for enjoyment or profit. If the dugout is constructed properly and in a suitable location, very little maintenance is required. If algae, vegetation or suspended solids become problems, then control can be either chemical (copper sulphate, diquat, aluminum sulphate, etc.), mechanical (uprooting weeds with chains) or biological (grass carp). Care must be taken in dugouts used for fish culture, as some of the chemical applications are directly toxic to the fish or result in decomposing plants that ultimately deplete the oxygen needed by the fish.

Description

Parasitic roundworms, or nematodes, are found year-round in cattle in Alberta. These parasites live in many sites including: lungs ; body cavity ; tear or lacrimal ducts ; beneath the skin ; gastro-intestinal tract. Each area is occupied by roundworms specific to those sites. Cattle producers should be aware of the more important worms that can live in their cattle.

Description

Dryland saline seeps can be controlled using structural or biological controls. Structural controls for discharge areas include surface water management, subsurface water management and relief wells. Generally, structural controls lower water tables and improve accessibility in discharge areas faster than biological controls. However, structural controls are usually more expensive than biological controls and are not always totally effective.

Description

This fact sheet provides information for estimating probable freezing dates for 114 locations in Alberta. Average dates of frost occurrence have often been used for this purpose. However, averages have limited value because they denote the 50 per cent risk level or the probable occurrence of untimely frost in, for example, five out of ten years. This may well be too much risk for economic viability in the long run. On the other hand, trying to avoid all frost damage by sticking to a limited number of hardy, short-season crops may not be profitable either. The indirect costs of lost opportunities could be very high. For planning purposes, it may be better to use an intermediate risk level, such as 25 per cent, where the advantages of growing a particular crop outweigh the risks of occasional frost damage.

Description

Body condition, or the amount of body fat an animal is carrying, is one management indicator that can be used to predict herd fertility and determine feeding programs. This fact sheet is intended to make producers aware of the condition scoring system, what effects various condition scores will have on herd fertility, and to offer some management strategies regarding feeding and when to condition score to optimize both fertility and economics.
